Kajian Kualitas Air Lindi Terhadap Kualitas Air Tanah Menggunakan Metode Indeks Pencemaran (IP) dan Storet di TPA Tadukan Raga, Kabupaten Deli Serdang, Provinsi Sumatera Utara

Abstract

Organic waste at this landfill decomposes easily and produces leachate. If not properly managed, this leachate can contaminate the soil and groundwater around the landfill. This study aims to evaluate the quality of leachate and groundwater around the landfill using the Pollution Index and STORET methods in accordance with Ministry of Environment Regulation No. 115 of 2003. The groundwater quality status, assessed using the Pollution Index and STORET methods, indicates that the groundwater quality around the landfill meets the quality standards and is not contaminated by leachate. No significant differences were found between the groundwater quality of the monitoring wells and the residents' bore wells
